Application filed June 1, 1909. Serial No. 499,469.

a citizen of the United States, residing at Worcester, in the county ofWorcester and Liommonwealth of Massachusetts, have invented a new anduseful Improvement in Manure-Spreaders, of which the following is aspecification, accompanied by drawings forming aspart of the same, inwhich- Figure 1 is a side view of a manure spreader embodying myinvention. Fig. 2 is the same view showing the opposite side. Fig. 3 isa plan view. Fig. 4c is a rear view. Fig; 5 is arear View of the bodyandsuport'mg wheels, with the beaters, the movable bottom and theiractuating mechanism 1 wheel shafts, in the present instance,

Similar reference lar parts in the different figures.

My invention relates to that class of manure spreaders which areprovided with a rotating beater at the rear end of the body bf thespreader for distributing the manure, and it consists in theconstruction and arrangement of parts as hereinafter de scribed andpointed out in the. annexed claims. 7

Referring to the accompanying drawings, 1 the of a manure spreadersupported on forward wheels 2 and rear wheels 3. The rear wheels 3 arecarriedupon a cranked axle 4., upon which the body 1 is supported in aplane below the center of the rear wheels The body 1 is provided with amovable bottom 5 carried on sprocket wheels 6, 6 which are attached totransverse shafts 7, 7*.

The movement of the bottom 5 is accomplished by the rotation of one ofthe sprocket the shaft 7, which carries a worm gear 8 on one end engagedby a worm 9 on a short shaft 10 which is capable of swinging from oneend about the axis of a shaft 11, which extends beneath the body 1 andtransversely thereto.

The short shaft 10 carries an adjustable p nion 12, which 18 driven byone of the crown gears 13, 13 on the side of a sprocket wheel 14 on oneend of the shaft 11. The

opposite end of the shaft 11 is also we.

characters, refer to simi- I posite direction.

.When the heaters are vided with a sprocket wheel 15. The sprocketwheels 14 and 15 are driven through chain connections by sprocket wheels16, 16, attached to sleeves 17, 17 which rotate about the axle 4 betweenthe body 1 and the wheels 3. 3. The sleeves 17, 17, are driven in onedirection from the wheels 3, 3, by means of ratchet wheels 18 attachedto the sleeves and pawls 19 carried by the wheels 3, 3. The worm andworm wheel mechanism driven by the crown gears 13 or 13 according to thedesired speed of the movable bottom, is substantially like thecorresponding bottom driving mechanism shown in United States LettersPatent No. 268,410, dated December 5, 1882, and forms no part of mypresent invention.

Projectingrearwardly from the body portion 1 is a frame 20, in which arejournaled the shafts of vertical heaters 21 arranged to spread themanure contained in the body, and which is carried into contact with theheaters 21 by the movable bottom 5. J ournaled in bearings 22 supportedbeneath the frame 20 is a horizontal shaft'23 provided with bevel gears24, arranged to engage bevel gears 25 upon the. lower. ends of thebeater shafts 26. A pair of bevel gears 27, with their faces in oppositedirections, are carried upon the shaft 23, capable of being substitutedfor the bevel gears 24 when it is desired to rotate the heaters 21 inthe op- Mounted upon each end of the horizontal shaft 23 is a sprocketwheel 28 driven from sprocket wheels 29 carried by the sleeve 17Avertical row 30 of horizontal teeth is arranged in each rear innercorner of the frame 20, to cooperate with the teeth of the revolvingheater in pulverizing the manure, as shown in Fig. 3.

In order to control the distribution of manure as it is distributed bythe heaters, I provide curved shields 30 attached at one end to theframe 1 and curving inward as shown in Fig. 3. The shields are of awidth sufficient to intercept the lateral flight of a due proportion ofmanure and deposit it behind the beater. The arrangement of the shields30, shownin for the inward rotation of the heater in the direction ofthearrows 31'in that figure.

to rotate in the opposite direction, accomplished by driving the heatersby the beveled gears 27 instead of Fig. 3, is designed is changed andthey are attached to the vertical post '32 at the rear of and betweenthe outward, will be turned inwardly and heaters, as shown by dottedlines 33 in Fig. 3. lVhen the shields are in the position shown at thesides, a portion of the manure, which would otherwise be directedlaterally caused to fall behind the center of the body. When the shieldsare supported on the post 32, the manure thrown against the shields isde-' flected outwardlyalffihe'shields may be used to deflect the manurein one direction only,

if desired. The amount of manure deflected.

will depend upon the width of the shields and this may be varied asdesired.

I have shown two ve'rt'cal heaters, but the number may be varied iffound desirable. By the use of heaters placed at an angle other thanhorizontal, as is usual, I distribute the manure over a space wider thanthe width of the body and thereby increase the efliciency of thespreader. Each vertical row 30 of teeth is supported upon posts'34 which.are attached to rods 35 pivoted in the framework of the spreader. Theteeth are maintained in positionto point toward the center of the heater21 by means hf a spring 36, attached at one endto a lever 37 ,carried bythe upper end of the rod 35, with-its opposite end attached to theframework. The post 34 is, therefore, yieldinglyheld. against-a stop 38,and is capable of swinging when too great pressure is applied tothey-tow 30 of teeth, As the manure is caught by the teeth ofthe heater,it is forced between the row 30 of teeth and shredded, or pulverized.

I claim, 1. A manure spreader, comprising a body, a movable bottom forsaid body, and a re;

' tatable beater above the plane of said movable bottom with the axis ofrotation of said Gdpies of this patent may be obtained. for

beater at an angle to the horizontal.

2. A manure spreader, "comprising a body, a movable bottom, and avertical rotatable heater journaled at the rear end of said body abovesaid movable bottom.

3. A manure spreader having a body, supporting wheels for the rear ofsaid body, a

movable bottom, a rotatablebeater vertical above the plane of saidmovable bottom, and a 2 intermediate connecting mechanism between saidbeater and said supporting wheels.

4:. A manure spreader having a body with a movable bottom arranged toreceive the manure, a vertical beater journal ed at the able bottom andat an angle to the horizon-i tal plane of said movable bottom.

6. A manure spreader having a body, sup porting wheels for the rear ofsaid body, with the bottom of said body supported at a plane below thecenter of said wheels, a frame attached to the rear of said body, avertical beater journaled in said frame above the plane of said bottom,a horizontal shaft beneath said beater for imparting rotation thereto,and means for connecting each end of said horizontal shaft with one ofsaid supporting wheels.

7. A'manure spreader, having a body, a rotatable vertical beatersupported by said body, a row of teeth supported by said body andarranged to cooperate with the teeth -of said beater, and means forrotating said beater.

8. A manure spreader having a body, a movable :bottom for said body, arotatable beater above the plane of said movable bottom, with the axisof rotation of said beater at an angle'to the.horizontal, and curvedshield plates on opposite sides of saidbody above the'plane of saidmovable bottom and extending rearwardly from the plane of said beater;

E 9. A manure spreader, having a body, a

end of said body, and a shield plate support at the rear of and in aplane between said heaters.
